HW Detector Status
• FMD3 installed– fully HW tested
• FMD2 installed– initially HW tested– Full testing with miniframe
(~Nov.)
• FMD1 not yet installed– Installation ~Feb.

Geometry
• Geometry consists of TGeo objects• Geometry constructed by half-rings
(for alignment)• FMD3
– All material described
• FMD2– Most material described
• Some support structure missing
• FMD1– Support needs better description
• Check of final positions necessary

Calibration
• 2 types of calibration necessary– Pedestals– Gains
• Gains taken in standalone run– Procedure implemented on FE Firmware– Injects known charge into pre-amplifiers
• Pedestals can be done 2 ways– Standalone run with no beam– In beam run with past-future protection
ALICE Offline Week, 08/10/07 Kristján Gulbrandsen, NBI 5
Calibration procedure
• Pedestal and Gain Finders written for standalone runs– Ped. - normal run, no beam– Gain - special run– Not in Aliroot– Need info from DCS
• Fx. Oversampling
– Need DCM from CDB– Possibly send peds to FEE

Shuttle
• Fetch files from FXS(s) and put in OCDB• Interact with DAQ and DCS networks
– Not clear how to get info from DCS FE DB
• Procedure depends on new RCU Firmware

Other Open Tasks
• EVE Display– Stands as open task (because we didn’t do it)– Was this implemented by someone else?
• Digit Quality Assurance– Don’t know what should be done here - need input
• Survey Data Format– Only needed for FMD1– Will be done early next year
• HLT output– FMD has no HLT output

Planning
• Main goal is to prepare for dress rehearsal– Prioritize tasks based on this criterion
• Automatic procedures get high priority– For offline shuttle is most important
• Manpower– C. Holm must work on Ph.D. thesis until Jan.– Offline work hopefully to be done by current
research assistant (prospective Ph.D. student)
